What is digits constant in Python?

The string module

The string module in Python is a collection of different constants.

The digits constant

The digits constant in the string module contains the digits from 0 to 9 in the form of a string.

The value of the constant is as follows:

0123456789

Syntax

string.digits

Since digits is a constant, we can access it via the string module.

Let’s look at two code examples that use the digits constant.

Example 1

Explanation

• Line 1: We import the string module.

• Line 3: We store the output of string.digits in the variable called digits_output.

• Line 5: We print the variable digits_output.

Example 2

Explanation

• Line 1: We import the string module.

• Lines 3–9: We define a function called contains_digits that accepts a string as its parameter and checks whether this string has any digits or not.

• Line 11: We define a string called str_to_check_1 that contains only ASCII letters.

• Line 12: We invoke the contains_digits function by passing str_to_check_1 as a parameter.

• Line 14: We define a string called str_to_check_2 that contains digits and ASCII letters.

• Line 15: We invoke the contains_digits function by passing str_to_check_2 as a parameter.
